It's still basically the same though. Mollies may or may not have multiple batches inside of them, we don't know yet, but I'd imagine it's pretty similar to the Guppy, seeing as they are in the same family. They still have about a month long gestation, though it can take up to 2 months. 4-6 weeks is more common. And the time in between is basically non-existant too, unless they are seperate from males and have worn out the saved up sperm.
